For example, a country could allow free trade with another country, with exceptions that prohibit the importation of certain drugs that have not been approved by its regulators, or animals that have not been vaccinated, or processed foods that do not meet their standards. Few questions separate economists as much as the general public as free trade. Research suggests that economists at U.S. universities are seven times more likely to support free trade policies than the general public. In fact, the American economist Milton Friedman said, „The business profession was almost unanimous about the desirability of free trade.“ The creation of trade and the diversion of trade are crucial effects that are identified in the establishment of a free trade agreement. The creation of businesses will shift consumption from a low-cost producer to a low-cost producer, and trade will therefore grow. On the other hand, trade diversion will shift trade from a lower-cost producer outside the territory to a more expensive producer under the free trade agreement.  Such a change will not benefit consumers under the FTA, as they will be deprived of the opportunity to purchase cheaper imported products. However, economists note that trade diversion does not always harm aggregate national welfare: it can even improve aggregate national welfare if the volume of diverted trade is low.
